I had a 5 year old Shar Pei that on a sunday night was very normal. Upon waking up Monday morning she was very listless. I took her to the vet and her heart and lungs were fine. Blood work was done and she showed a low white blood count. She deteriorated during the day and I stayed up with her all night. At 7:50 am Tuseday she passed away. At no time did she show any pain except the last 1/2 hour she was whimpering.
Does anyone have any idea why a seemingly normal healthy dog would pass away so quickly at such a young age?
